Circumference Circumference of a circle[edit] Circle illustration with circumference (C) in black, diameter (D) in cyan, radius (R) in red, and centre or origin (O) in magenta. Circumference = π × diameter = 2 × π × radius. The circumference of a circle is the distance around it. The term is used when measuring physical objects, as well as when considering abstract geometric forms. When a circle's diameter is 1, its circumference is π. When a circle's radius is 1—called a unit circle—its circumference is 2π.

- Circumference of a circle is the linear distance calculated along its edge. It is similar to perimeter of a geometric figure, but the term 'perimeter' is rather used to describe the property of polygons.

Driving from and to â Calculate time and distance If one centimeter equals 150 miles and the distance is 1.75 cm then the straight distance between these two points is 150 x 1.75 equals 262.50 miles. But we know that very few roads are built straight from one point to another point. So, you measure between landmarks.

- 2. If you know the circumference of the circle, divide it by π to get the diameter. π is equal to approximately 3.14 but you should use your calculator to get the most accurate results. For example, if the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm.he radius is the distance from the center of the circle to its edge. For example, if the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm.

Circumference In geometry, the circumference (from Latin circumferentia, meaning carrying around) of a circle is the (linear) distance around it. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.

History of geodesy The circumference of the Earth is 24,902 mi (40,075.16 km). Over the poles it is more precisely 40,008 km or 24,860 mi. The actual unit of measure used by Eratosthenes was the stadion. No one knows for sure what his stadion equals in modern units, but some say that it was the Hellenic 185 m stadion.

Central Angles and Arcs It is the central angle's ability to sweep through an arc of 360 degrees that determines the number of degrees usually thought of as being contained by a circle. Central angles are angles formed by any two radii in a circle. The vertex is the center of the circle. In Figure 1, ∠ AOB is a central angle.

Circle The radius is the distance from the center of the circle to its edge. For example, if the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. 2. If you know the circumference of the circle, divide it by π to get the diameter. π is equal to approximately 3.14 but you should use your calculator to get the most accurate results. For example, if the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm. 3. If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter.

What is the distance around the world on the equator? What is the circumference of the Earth? How far around is the Earth? The average radius of the Earth is 3,959 miles (6,374 kilometers). The equitorial diameter of the Earth (distance from one side of the Earth to the other at the equator) is about 7,926 miles. The ratio of the circumference to the diameter of a circle (circumference/diameter) is written as the symbol pi. Pi is approximately 3.141592.

- After great debate, the international standard set a nautical mile as 6,076 feet. A statute mile consists of 5,280 feet. Thus, doing the math (6,076*21,600/5280) we find the circumference of the earth to be 24,856.36364 statute miles when using this method. statute mile is the straight line distance between the t … wo, not taking into account the curvature of the earth. Because the straight line distance between two points is shorter than a curved path between them, a statue mile is 5280 feet while a nautical mile (at the equator) is 6076 feet.

How to Calculate the Area & Circumference of a Circle As noted above, the circumference of a circle is the length of the line around the edge of the circle. A circle's circumference, c, is equal to twice its radius, r, times π. To calculate circumference, then, you multiply the circle's radius by 6.28. Take a circle with a radius of 4 inches.

Circumference of a Circle The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter. Thus, the diameter of a circle is twice as long as the radius.

Circle The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c). A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d). Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r). The circumference of a circle is found using this formula: Example: Find the circumference of the circle: Video lesson: Find the radius of the circle. 1  Pre-Algebra. 2  Algebra 1. 3  Algebra 2. 4  Geometry. 5  Sat.

Distance Distance is a numerical description of how far apart objects are. In physics or everyday usage, distance may refer to a physical length, or an estimation based on other criteria (e.g. two counties over). In most cases, distance from A to B is interchangeable with distance from B to A. In mathematics, a distance function or metric is a generalization of the concept of physical distance.

Instant Length Unit Conversions Our length or distance conversion tool could be very useful during traveling. Though, the most common metric used for distance calculation is Kilometer but in some places miles is also used and 1 mile equals to 1.6 kilometers. During traveling around the city or out of the country, one can easily convert distances as per the requirement.
